| Abstract: |
| Shaking flask tests of bioleaching under different acid consumption, L/S and initial iron concentration were carried out for low grade hard rock type uranium ore. The relationship between uranium leaching rate and acid concentration, ferric iron concentration of bacteria liquid, L/S, and Eh was investigated. The optimum technical parameters include acidification acidity of 30~60 g/L, acid consumption of 8%~15%, L/S of (2.5~5.0)︰1, and ferric iron concentration of 5~7 g/L. |
